SPECIFICATION forming part of Letters Patent No. 516,653, dated March20, 1894.

Application led May 23.1893.

To ZZ whom it may concern.:

Be it known that I, LORENZO FLOOD LARY, a citizen of the United States,residing at Pottersburg, in the county of Union and State of Ohio,haveinvented certain new and useful Improvements in Gravity-Batteries;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in that class of galvanicbatteries, known as gravity batteries, and it has for its general objectto provide a battery embodying such a construction that a space isafforded at the bottom of the cell for the sulphate of zinc so as toprevent the loss of copper by deposit on such particles and keep thecopper solutionl free from foreign matter.

Another object of the invention is to provide a copper electrode adaptedto serve as a receptacle for theblue vitriol, and embodying such aconstruction that it may be spread out at when removed from the cell soas to facilitate the removal of copper formations.

Other objects and advantages of the invention will appear from thefollowing description and claims when taken in connection with theaccompanying drawings, in which- Figure l, is a vertical, diametricalsection of a battery embodying my invention. Fig. 2, is a plan view ofthe copper electrode in the shape it assumes when placed in the cell,and Fig. 3, is a view illustrating the copper electrode as spread out soas to facilitate the removal of copper formations.

Referring by letter to said drawings:-A, indicates a cell which may beof any approved form and construction, and B, indicates the zine ornegative electrode which may be of the well known crows foot, or otherpattern. This electrode is preferably provided with `a hook a, as shown,whereby it is supported in the cell, and it is connected to the circuitwire b, through the medium o'fthe binding post c, or in any otherapproved manner.

C, indicates the copper or positive electrode of the battery which isdesigned to rest upon the bottom of the cell and serve as a receptaclefor the blue vitriol or equivalent exciting substance, indicated by D.In forming this Serial No. 475389. (No model.)

copper electrode C, I take a sheet of copper and cut it so as to' form agenerally elliptical ligure, that is one having one of its longitudinaledges and its ends rounded as shown at d, and e, and havinga segmentremoved from its other longitudinal edge. I then provide the sheet witha large aperture g, and aseries of comparatively small apertures h,after which I slitit as illustrated to form the tongue supportf.` I thenbend the sheet as shown in Fig. 2, so as to form the inverted cone (seeFig. 3,) having the aperture g, at its lower end, and I also bend thetongue f, outwardly, as illustrated in the said figure, so that itserves to support the'electrode above the bottom of the cell.

In addition to the tongue supportf, I provide the cone shaped electrodewith a prop or support as t; and, if necessary, the said electrode maybe further supported-by bending the circuit wirej, over the upper edgeof the cell.

In the practice of my invention, the cone shaped electrode, charged Witha sufficient quantity of blue vitriol, or other excitant, is placed inthe cell as shown in Fig. l, so as to form a chamber or space at thebottom of the same. The zinc or negative electrode is then placed inposition, after which the liquid is added.

In the practice of my invention, I prefer to employ a cone shaped copperelectrode formed in the manner herein illustrated and described, as thesame is advantageous, but I do not desire to be understood as confiningmyself to an electrode formed in such manner, nor do I want to beconfined to an electrode of cone shape as any approvedshape of electrodemay be employed that will serve at once as a receptacle for the excitantand to form a chamber at the bottom of the cell.

Having described my invention, what I claim isl. The electrode O, formedby asheet of material bent or furled into cone shape, and having anaperture in its bottom; said electrode being adapted to serve as areceptacle for an excitant and being also adapted to be unfurled andflattened out so as to facilitate the removal of chemical formations,substantially as specified.

2. The combination with a cell and an zinc IOO or negative eiectroearranged therein; of a Intestimony whereof I afx my signature in copperor positive electrode formed by bendpresence of two witnesses. ing asheet of copper into cone shape; said electrode having an aperture atits bottom Y LORENZO FLOOD LARY 5 and also having the integral support'Jf, and Witnesses:

the support substantially as and for the ORLANDO BURL EATON purpose setforth. LESTER WARE CLINE.
